听力原文：M: Hello, Mary. I was hoping to speak to Helen. W: Sorry, Helen's away on business. Can I help? M: Yes, Mary, I think you probably can. I'm afraid I've got some rather bad news. W: Oh? M: It's the trip over for Electronica. W: Uh-huh? M: Yes, I'm afraid we've had a bit of an internal reorganization here and we'll be sending a much smaller team. W: You will still be having the same booth at the fair, won't you? M: I'm afraid not. There'll be just Brine and myself so we won't be able to manage such a large booth. W: Well, I can't promise that they're going to have any smaller booths available at this late date ... M: Yes, I realize that. But could you see what you could do? You know, Mary, you've done a terrific job so far. W: We've certainly put a lot of work into it. I hope this doesn't mean you're canceling the reception at Caesar's Restaurant? M: Not canceling it, but I think we'll have to reduce the scale a bit. W: The problem is that all the arrangements have all been made and confirmed. We've already given a deposit for the food and wine. I don't know ... this may be difficult to change ... M: Yes, I know, I'm sorry, but these things happen. I think I'd better talk to Helen. W: Yes, I think you should. (20)
